在一个Hibernate查询中更新几个列？

Question

我有以下HQL:

String hql = "UPDATE Buchung as b " +
             "set STORNO = :Storno " +
             "where ID = :BuchungID";

是否可以在HQL中更新多个列？例如:

String hql = "UPDATE Buchung as b " +
              "set STORNO = :Storno " +
              "set NAME = :Name " +
               ......  
              "where ID = :BuchungID";

我知道如何在MSSQL中这样做,但我不知道如何在Hibernate中做到这一点.

在这种情况下,HQL与SQL没有什么不同.只需使用逗号分隔列:

String hql = "UPDATE Buchung as b set " +
          "STORNO = :Storno," +
          "NAME = :Name " +
           ......  
          "where ID = :BuchungID";
